Don't print out default value if empty string in PHP Barcode Generator Script


Hi!

Thank you for a very nice script. There is just one thing that bothers me a bit. I have made a textbox to fill in a number, and then get the barcode for this.

I wish that there will not be any barcode if that field is empty. In the $options = array part of the script, there is a default text that becomes the barcode. If I remove the text that is the default, there is still generated an empty barcode. How can I change this to not be a barcode at all?

Best regards

Because the PHP Generator Script displays a default number value when no data is encoded, it is not possible to create a blank canvas. However, it may be possible to check for a null value and if null, set the img src to a blank image/white image. Or something similar.

<?php if($_datatoencode->getAttributeText('datatoencode') !== null): ?>
<div class="datatoencode1"><img src="nullimage.jpg">
<?php endif; ?>
